Nope, this is not a thread on how Pieces of SEVEN fails as in interlude.
I don't know if anyone feels like this, but I feel these 3 songs are connected.
For one, do you realize LOVE 'n' HATE and Days are very similar? They both talk about the feelings faced when you have a crush! But LOVE 'n' HATE is the more sexy/edgy outlook to it, while Days is the more demure and tamed outlook.
Some comparison...
"I knew from the start
That it's really impossible
Even so ..."
LOVE 'n' HATE
vs
"I've known for a long time that you have someone precious
Because it's clear from your smile"
Days
Also, another thing to note is this:
"I only wanted to dream
That my dream would come true
Just for a moment"
LOVE 'n' HATE
Yeah, a dream. And what happens in the Days PV? She dreams~
Well, I think both songs are having a crush on someone who already is attached or something. I might even go to the extent of saying she might have a crush on someone gay (yeah let's bring the ayuxshu-ya fanshipping to it ultimate!

)... impossible crush?
Now, that's not the main point. I just think LOVE 'n' HATE and Days are mirrors of each other. They both talk about the same thing, but in very different perspectives. It's like STEP you Ayu #2 and STEP you Ayu #3, if you get what I mean...
Now, how does Pieces of SEVEN connect these two?
Remember that in LOVE 'n' HATE, she sings about counting in the heart... "1 2 3 4 5 6 7 0", she counted 7 times (not 8, cos at the 8th beat, she sings 0 instead)... SEVEN much.
Also, in the Days PV, when Ayu was in her 'dream' with Shu-ya, she woke up at 6am. When she was in 'reality', she woke up at 8 01am. Disregarding that one minute, we can say that the times were 6am and 8am respectively.
So what's the number in between? SEVEN.
I seriously now think that Pieces of SEVEN is a good connection between LOVE 'n' HATE and Days. Lol... pardon me for this, but I can't help it when my favorite album track, favorite interlude and favorite single song/song in general is lined up after one another!
